| NAME |
| ---- |
| git-index-pack - Build pack index file for an existing packed archive |
| |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'git index-pack' [-v] [-o <index-file>] [--[no-]rev-index] <pack-file> |
| 'git index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>] |
| [--[no-]rev-index] [<pack-file>] |
| |
| |
| DESCRIPTION |
| ----------- |
| Reads a packed archive (.pack) from the specified file, and |
| builds a pack index file (.idx) for it. Optionally writes a |
| reverse-index (.rev) for the specified pack. The packed |
| archive together with the pack index can then be placed in |
| the objects/pack/ directory of a Git repository. |
| |
| |
| OPTIONS |
| ------- |
| -v:: |
| Be verbose about what is going on, including progress status. |
| |
| -o <index-file>:: |
| Write the generated pack index into the specified |
| file. Without this option the name of pack index |
| file is constructed from the name of packed archive |
| file by replacing .pack with .idx (and the program |
| fails if the name of packed archive does not end |
| with .pack). |
| |
| --[no-]rev-index:: |
| When this flag is provided, generate a reverse index |
| (a `.rev` file) corresponding to the given pack. If |
| `--verify` is given, ensure that the existing |
| reverse index is correct. Takes precedence over |
| `pack.writeReverseIndex`. |
| |
| --stdin:: |
| When this flag is provided, the pack is read from stdin |
| instead and a copy is then written to <pack-file>. If |
| <pack-file> is not specified, the pack is written to |
| objects/pack/ directory of the current Git repository with |
| a default name determined from the pack content. If |
| <pack-file> is not specified consider using --keep to |
| prevent a race condition between this process and |
| 'git repack'. |
| |
| --fix-thin:: |
| Fix a "thin" pack produced by `git pack-objects --thin` (see |
| linkgit:git-pack-objects[1] for details) by adding the |
| excluded objects the deltified objects are based on to the |
| pack. This option only makes sense in conjunction with --stdin. |
| |
| --keep:: |
| Before moving the index into its final destination |
| create an empty .keep file for the associated pack file. |
| This option is usually necessary with --stdin to prevent a |
| simultaneous 'git repack' process from deleting |
| the newly constructed pack and index before refs can be |
| updated to use objects contained in the pack. |
| |
| --keep=<msg>:: |
| Like --keep create a .keep file before moving the index into |
| its final destination, but rather than creating an empty file |
| place '<msg>' followed by an LF into the .keep file. The '<msg>' |
| message can later be searched for within all .keep files to |
| locate any which have outlived their usefulness. |
| |
| --index-version=<version>[,<offset>]:: |
| This is intended to be used by the test suite only. It allows |
| to force the version for the generated pack index, and to force |
| 64-bit index entries on objects located above the given offset. |
| |
| --strict:: |
| Die, if the pack contains broken objects or links. |
| |
| --progress-title:: |
| For internal use only. |
| + |
| Set the title of the progress bar. The title is "Receiving objects" by |
| default and "Indexing objects" when `--stdin` is specified. |
| |
| --check-self-contained-and-connected:: |
| Die if the pack contains broken links. For internal use only. |
| |
| --fsck-objects:: |
| For internal use only. |
| + |
| Die if the pack contains broken objects. If the pack contains a tree |
| pointing to a .gitmodules blob that does not exist, prints the hash of |
| that blob (for the caller to check) after the hash that goes into the |
| name of the pack/idx file (see "Notes"). |
| |
| --threads=<n>:: |
| Specifies the number of threads to spawn when resolving |
| deltas. This requires that index-pack be compiled with |
| pthreads otherwise this option is ignored with a warning. |
| This is meant to reduce packing time on multiprocessor |
| machines. The required amount of memory for the delta search |
| window is however multiplied by the number of threads. |
| Specifying 0 will cause Git to auto-detect the number of CPU's |
| and use maximum 3 threads. |
| |
| --max-input-size=<size>:: |
| Die, if the pack is larger than <size>. |
| |
| --object-format=<hash-algorithm>:: |
| Specify the given object format (hash algorithm) for the pack. The valid |
| values are 'sha1' and (if enabled) 'sha256'. The default is the algorithm for |
| the current repository (set by `extensions.objectFormat`), or 'sha1' if no |
| value is set or outside a repository. |
| + |
| This option cannot be used with --stdin. |

| NOTES |
| ----- |
| |
| Once the index has been created, the hash that goes into the name of |
| the pack/idx file is printed to stdout. If --stdin was |
| also used then this is prefixed by either "pack\t", or "keep\t" if a |
| new .keep file was successfully created. This is useful to remove a |
| .keep file used as a lock to prevent the race with 'git repack' |
| mentioned above. |
